PROBLEM TO BE SOLVED: To provide a pachinko machine with a rear gutter which can be precisely attached to the rear side of the pachinko machine even if the finishing of position determining holes formed on the rear side of the pachinko machine is not so good. SOLUTION: Position determining holes 181, 182 as shown in the figure (a) are formed on the rear side of the game board of this pachinko machine, and position determining holes 183, 184 as shown in the figure (b) are also formed. As shown in the figure (a), a through-hole D, piercing through both front/rear sides of the game board is formed. A protrusion T with a hollow part P communicating with the through-hole D protrudes from around the through-hole D in the ear parts M5, M6. As shown in the figure (b), a through-hole (d) like the through-hole D is formed, and a position determining protrusion (t) with a hollow part (p) like the hollow part P protrudes from around the through-hole (d) in the ear parts m5, m6. |
